Hospitals can/do make you sicker

S. aureus is the most common cause of hospital-acquired infections, and can cause inflammation of the heart, toxic-shock syndrome and meningitis.
Methicillin-resistant Staph broke out in a British hospital in December and killed two patients with a new type of pneumonia called necrotizing pneumonia. This infection destroys lung tissue and also kills some of the immune system cells sent to battle it.
“The pneumonia itself is very severe,” Bowden said. “There is massive inflammation and there is fluid in the lungs and there is damage to the tissue. It can progress very quickly and in 72 hours the patient can be in a severe condition, or it can even be lethal in 72 hours.”
